Detailed Description
The optical system of the embodiment of the present disclosure is explained below. However, it can be readily appreciated that the disclosed embodiments provide many suitable authoring concepts that can be implemented in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the disclosure, and do not limit the scope of the disclosure.
Furthermore, relative terms, such as "below" or "bottom" and "above" or "top," may be used in embodiments to describe one element's relative relationship to another element of the figures. It will be understood that if the device of the drawings is turned upside down, components described as being on the "lower" side will be components on the "upper" side.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, materials and/or components, these elements, materials and/or components should not be limited by these terms, and these terms are only used to distinguish one element, material and/or component from another element, material and/or component. Thus, a first element, material, and/or section discussed below could be termed a second element, material, and/or section without departing from the teachings of some embodiments of the present disclosure, and unless specifically defined, any such first or second element, material, and/or section in the claims below can be understood to be any element, material, and/or section in the specification that comes within the claims.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Furthermore, the terms "substantially", "about" or "approximately" are also recited herein, and are intended to cover both substantially and completely consistent conditions or ranges. It should be noted that, unless otherwise defined, even if the above-mentioned terms are not described in the description, they should be interpreted in the same sense as if the above-mentioned approximate terms were described.
FIG. 1 shows a perspective view of an optical assembly drive mechanism 16-101 according to one embodiment of the present disclosure. It should be noted that, in the present embodiment, the optical device driving mechanism 16-101 is, for example, a Voice Coil Motor (VCM), which can be disposed in an electronic device with a camera function for driving an optical device (e.g., a lens) and has an Auto Focus (AF) function. In addition, the optical module driving mechanism 16-101 has a substantially quadrangular structure, and the outer frame 16-110 thereof has a top surface 16-111 and four side walls 16-112 extending from edges of the top surface 16-111. Openings 16-113 are provided in the top surfaces 16-111 corresponding to optical components (not shown). I.e., the optical axis 16-O, passes through the opening 16-113 so that light can enter the optical element driving mechanism 16-101 through the optical axis 16-O. In some embodiments, the sidewalls 16-112 extend in a direction (Z-axis) perpendicular to the optical axis 16-O. In some embodiments, sidewalls 16-112 extend from edges of top surface 16-111 in a direction that is non-parallel to optical axis 16-O.
Fig. 2 shows an exploded view of the optical assembly drive mechanism 16-101 shown in fig. 1. As can be seen from FIG. 2, the optical assembly driving mechanism 16-101 mainly comprises a housing 16-110, a base 16-120, a movable portion 16-130, a first driving assembly 16-140, a frame 16-150, a first elastic assembly 16-161, a second elastic assembly 16-162, a circuit board 16-170, and a sensing assembly 16-180. In addition, the outer frame 16-110, the base 16-120, the frame 16-150 and the circuit board 16-170 may constitute a fixing portion 16-F. The outer frame 16-110 and the base 16-120 can be connected to each other and combined into a hollow box, so that the movable portion 16-130, the first driving component 16-140, the frame 16-150, the first elastic component 16-161, and the second elastic component 16-162 can be surrounded by the outer frame 16-110 and accommodated in the box. Thus, the outer frames 16-110, the frames 16-150 and the bases 16-120 are arranged in sequence along the optical axis 16-O. In other words, the light sequentially passes through the outer frames 16-110, the frames 16-150 and the bases 16-120 to the image sensors 16-102 (as shown in FIG. 4) disposed outside the optical assembly driving mechanisms 16-101, thereby generating images.
The movable portion 16-130 has a hollow structure and carries an optical assembly having an optical axis 16-O. The frames 16-150 are disposed on the bases 16-120 and fixed to the outer frames 16-110. In addition, the movable portion 16-130 is movably (movably) connected to the outer frame 16-110 and the base 16-120. The first elastic component 16-161 is disposed between the outer frame 16-110 and the movable portion 16-130, and the second elastic component 16-162 is disposed between the movable portion 16-130 and the base 16-120. More specifically, the movable portion 16-130 can be connected to the outer frame 16-110 and the base 16-120 through the first elastic element 16-161 and the second elastic element 16-162 made of metal respectively, so as to movably suspend the movable portion 16-130 between the outer frame 16-110 and the base 16-120, and the movable portion 16-130 can move along the optical axis 16-O between the outer frame 16-110 and the base 16-120. For example, the first resilient member 16-161 and the second resilient member 16-162 are made of metal or any other suitable resilient material.
The first driving assembly 16-140 includes two sets of first coils 16-141 and first magnetic assemblies 16-142, wherein the first coils 16-141 can be disposed on the movable portion 16-130, and the first magnetic assemblies 16-142 can be disposed on the frame 16-150. When a current is applied to the first coil 16-141, an electromagnetic driving force (electromagnetic driving force) can be generated by the first coil 16-141 and the first magnetic element 16-142 to drive the movable portion 16-130 and the optical element carried by the movable portion to move along the Z-axis (i.e., the optical axis 16-O) relative to the base 16-120, so as to perform an auto-focus (AF) function. In other embodiments, the positions of the first coil 16-141 and the first magnetic assembly 16-142 may be interchanged. In other words, the first coil 16-141 can be disposed on the frame 16-150, and the first magnetic element 16-142 can be disposed on the movable portion 16-130, so as to achieve the automatic focusing effect.
In addition, the first driving assembly 16-140 further includes a second coil 16-143 and a second magnetic assembly 16-144, wherein the second coil 16-143 can be disposed on the movable portion 16-130, and the second magnetic assembly 16-144 can be disposed on the frame 16-150. In this embodiment, when a current is applied to the second coil 16-143, an electromagnetic driving force (electromagnetic driving force) can be generated by the second coil 16-143 and the second magnetic element 16-144 to drive the movable portion 16-130 and the optical element carried by the movable portion to rotate relative to the fixed portion 16-F, so that the optical element driving mechanism 16-101 can be optically calibrated, or the optical element driving mechanism 16-101 can receive light from different locations.
In this embodiment, the first coil 16-141 and the first magnetic element 16-142 are disposed on opposite sides of the optical element driving mechanism 16-101, and the second coil 16-143 and the second magnetic element 16-144 are disposed at corners of the optical element driving mechanism 16-101. As such, the first coil 16-141 and the second coil 16-143 do not overlap as viewed in a direction parallel to the optical axis 16-O (the Z-axis). Furthermore, the first magnetic assembly 16-142 and the second magnetic assembly 16-144 do not overlap as viewed in a direction parallel to the optical axis 16-O.
The circuit board 16-170 is disposed on one side of the optical assembly driving mechanism 16-101 and is used to transmit electrical signals. For example, the optical device driving mechanisms 16-101 can control the position of the optical device according to the electrical signal to perform auto-focusing and other functions. In the present embodiment, the circuit members 16-121 are disposed in a mold-in (insert molding) manner in the bases 16-120 and are disposed to be electrically connected to the first driving elements 16-140. This can increase the variety of circuit designs of the optical module driving mechanisms 16 to 101. In addition, electronic components 16-171 may be disposed on circuit boards 16-170. By way of example, the electronic components 16-171 may be resistors, capacitors, inductors, or any other electronic component.
The sensing elements 16-180 include position sensors 16-181 and reference elements 16-182, wherein the position sensors 16-181 are disposed on the circuit boards 16-170, and the reference elements 16-182 are disposed within the movable portions 16-130. The position sensors 16-181 may detect changes in the magnetic field generated by the reference elements 16-182 to determine the position of the movable portions 16-130 and the optical elements. Thus, the first driving unit 16-140 can drive the movable portion 16-130 to move relative to the fixed portion 16-F according to the detection result of the position sensor 16-181. In some embodiments, one of the position sensor 16-181 and the reference component 16-182 is disposed on the stationary portion 16-F, and the other of the position sensor 16-181 and the reference component 16-182 is disposed on the movable portion 16-130.
Fig. 3 shows a cross-sectional view along the line B-B shown in fig. 1. As shown in fig. 3, the circuit board 16-170 and the circuit member 16-121 are exposed on different sides of the optical package drive mechanism 16-101. For example, the circuit board 16-170 and the circuit member 16-121 are exposed on opposite sides of the optical assembly drive mechanism 16-101. By the above design, the circuit boards 16-170 and the circuit members 16-121 are prevented from interfering with each other and affecting the operation of the optical assembly driving mechanisms 16-101.
Fig. 4A-4C show schematic diagrams of optical systems 16-100 according to an embodiment of the present disclosure. In this embodiment, the optical system 16-100 includes an optical assembly drive mechanism 16-101 and a corresponding image sensor 16-102, wherein the optical axis 16-O passes through the optical assembly drive mechanism 16-101 and the image sensor 16-102. As shown in FIG. 4A, light from the object 16-E enters the optical assembly drive mechanism 16-101 along the optical axis 16-O and reaches the image sensor 16-102. The image sensors 16-102 may receive the light to generate an image.
As shown in fig. 4B and 4C, the movable portion 16-130 is rotatable relative to the image sensor 16-102 so that the optical axis 16-O is not parallel to the arrangement direction (Z-axis) of the optical block drive mechanism 16-101 and the image sensor 16-102. Since the optical axis 16-O is deflected by the rotation of the movable portion 16-130, the size of the image sensor 16-102 is larger than the size of the optical components in the optical component driving mechanism 16-101. The image sensors 16-102 may receive light in different directions even if the optical axis 16-O is deviated. In this way, the image sensors 16-102 can receive a wider range of light, and process images generated by light from different angles, thereby achieving the functions of full-view image, wide-angle photography, and the like.
Fig. 5A-5C show schematic diagrams of optical systems 16-200 according to an embodiment of the present disclosure. In this embodiment, the optical system 16-200 includes an optical assembly drive mechanism 16-101 and a corresponding image sensor 16-103, wherein the optical axis 16-O passes through the optical assembly drive mechanism 16-101 and the image sensor 16-103. As shown in FIG. 5A, light from the object 16-E enters the optical assembly drive mechanism 16-101 along the optical axis 16-O and reaches the image sensor 16-103. The image sensors 16-103 may receive the light to generate images.
As shown in fig. 5B and 5C, the movable portion 16-130 can be rotated to deflect the optical axis 16-O. Further, the image sensor 16-103 is movable with respect to the rotation of the movable portion 16-130 so that the deflected optical axis 16-O passes through the image sensor 16-103. In this way, the image sensors 16-103 can receive a wider range of light and process the image to achieve functions of panoramic image, wide-angle photography, etc. Since the image sensor 16-103 can be moved according to the rotation of the movable portion 16-130, the size of the image sensor 16-103 can be not larger than that of the optical component in the optical component driving mechanism 16-101.
In this embodiment, the optical system 16-200 further includes a second driving component (not shown) configured to drive the image sensor 16-103 to move relative to the movable portion 16-130 according to an electrical signal generated by the sensing component (e.g., the sensing component 16-180). For example, the second driving element may be disposed outside the sidewall of the optical element driving mechanism 16-101, such that the first driving element 16-140 (shown in FIG. 2) and the second driving element do not overlap as viewed from the arrangement direction (Z axis) of the optical element driving mechanism 16-101 and the image sensor 16-103. In contrast, the first driving unit 16 to 140 overlaps the aforementioned second driving unit as viewed from a direction (e.g., Y axis) perpendicular to the arrangement direction of the optical unit driving mechanisms 16 to 101 and the image sensors 16 to 103.
Furthermore, in some embodiments, the image sensors 16-103 may be rectangular and have a long side (e.g., parallel to the X-axis) and a short side (e.g., parallel to the Y-axis) that are not parallel to each other, and the image sensors 16-103 move in a direction (Y-axis) parallel to the aforementioned short sides (as indicated by the arrows in FIGS. 5B and 5C). In some embodiments, the image sensors 16-103 may be square, circular, or any other suitable shape.
Fig. 6A-6C show schematic diagrams of optical systems 16-300 according to an embodiment of the present disclosure. In the present embodiment, the optical system 16-300 includes an optical assembly driving mechanism 16-101 and a corresponding image sensor 16-103, and a light transmission assembly 16-104, wherein the optical axis 16-O passes through the optical assembly driving mechanism 16-101, the image sensor 16-103 and the light transmission assembly 16-104. In some embodiments, the optically transparent members 16-104 are coupled to an optical member drive mechanism 16-101. For example, the light transmissive elements 16-104 may be apertures, shutters, or any other optical elements capable of passing light therethrough.
As shown in FIG. 6A, light from the object 16-E enters the optical assembly drive mechanism 16-101 through the optically transparent member 16-104 along the optical axis 16-O and reaches the image sensor 16-103. The image sensors 16-103 may receive the light to generate images.
As shown in fig. 6B and 6C, the movable portion 16-130 can be rotated to deflect the optical axis 16-O. In addition, the light transmissive member 16-104 is movable relative to the movable portion 16-130 for rotation such that the deflected optical axis 16-O passes through the light transmissive member 16-104. In this embodiment, the movement direction of the light-transmissive member 16-104 is opposite to the movement direction of the image sensor 16-103 (as indicated by the arrows in FIGS. 6B and 6C), so that the optical axis 16-O passes through the optical member driving mechanism 16-101, the image sensor 16-103, and the light-transmissive member 16-104. Thus, the optical system 16-300 can achieve the functions of full-view image and wide-angle photography.
In summary, embodiments of the present disclosure provide an optical system provided with an image sensor corresponding to an optical assembly driving mechanism. The disclosed embodiments provide various image sensor arrangement methods to cooperate with the movement of the optical assembly driving mechanism to image light. In addition, by designing a larger-sized or movable image sensor, a wider range of light can be received and the image can be processed to achieve functions of panoramic images, wide-angle photography and the like.
